An aphakic person also who is also hyperopic could be +30.00. ...Read moreSee 1 more doctor answer

No effect on sight: If you think of your eye as a camera, having a properly focused lens gives clearest picture possible, but the lens itself does not change the camera. The need for glasses comes from the eye not having the right shape or length. Glasses compensate for the physical abnormalities of the eye, but do not change the eye.

Not correct: Eyeglasses and contacts lens prescriptions are not the same. There is a power difference since the glasses are farther from the cornea surface compared to contact lens. Thus you need a different prescription, plus contact lens requires a base curve and diameter in addition to the power. ...Read moreSee 1 more doctor answer
Depends: Over the counter reading glasses assume both eyes are the same without astigmatic error. This is rarely the case.
